RADIATOR.

Application led February 19, 1918.

To all eli/1.0m t muy concern.'

Be it known that I, HORACE A. CRETON, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Radiator, of which the following vis a specification.

rllhis invention relates to a radiator and particularly pertains to that class of radiators employed in conjunction With internal combustion engines for cooling the circulating liquid employed in engine cooling systems.

The object of this invention is to provide a radiator of the above character comprising a series of radiator units, each of which units is built up of a series of superposed complementary elements or chambers adapted to be readily removed and replaced.

A further object is to provide a radiator so constructed and arranged that the liquid to be cooled may How rapidly and freely therethrough in large volume Without danger of being impeded by collections of sediment, and at the same time be distributed over a large cooling surface.

Other objects will appear hereinafter.

The invention is illustrated in the accompanying drawings, in which:

Figure 1 is a view in sectional elevation With parts broken away showing a pair of the radiator units as applied and illustrating the manner of assembling the units.

Fig. 2 is a plan view of one of the radiator units.

Fig. 3 is a View illustrating a modified form of the unit.

Fig. 4 is a view in sectional elevation showing a modified form of the unit.

Fig. 5 is a detail section of the element employed in said unit.

Fig. 6 is a plan view corresponding to Fig. 5.

Figs. 7 and 8 are plan views illustrating the further modified forms of the radiator elements.

In carrying out the invention a pair of upper and lower horizontally extending manifolds 10 and 11 are employed which communicate with the Water circulating system of internal combustion engines in the usual manner and between which manifolds my radiator elements 12 are detachably arranged. These radiator element-s are composed of a series of superposed units 13 consisting of substantially fiat hollow members Specification of Letters Patent.

formed with thinsheet metal, top and bottom Walls 14 and 15 joined together at their edges by a seam 16; openings 17 and 18 being formed inthe top and bottom Walls adapted to register With like openings in the Walls of the adjacent unit to form a passage extending vertically through the radiator element and forming an open communication between the successive units. The margins of the openings are pressed outwardly from the face 'of the unit Wall to form spacing collars 19 having fiat outer faces and tapered side Walls so that When the Walls of adjacent units are joined they Will be spaced apart except at the point of juncture of the collar. Joining of the adjacent units is effected by soldering the collars together. The lowermost unit seats on a plate20 having an opening through which the lower collar extends, this lower collar being affixed to a union coupling 21 having the usual threaded sleeve 22 adapted to be secured on a threaded nipple on themanifold 11. Secured to the plate 20 1s a pair of upwardly extending Walls 24 and 25 which connect at and extend along side the edges of the units and connect at their upper ends to a plate 26 attached to the top unit and having an opening through Which the upper collar 19 extends. This collar connects with the union coupling 27 having a threaded sleeve 28 adapted to `be secured on a threaded nipple 29 on the manifold 10. The Walls 24 and 25 are formed With ribs 30 which extend beneath the outer (fedges of the units and form supports there In the preferred form of the invention shown in Figs. 1 and 2 the openings 17 and 18 in the Walls of the units are oblong and the opening in one Wall isarranged at right angles to the opening in the other Wall with the centers of the openings in alinement. This forms a vertical passage leading from one manifold to the other through the radiator element. The openings being elongated, their end portions extend beyond the longitudinal edges of each other so that a portion of Wall will extend directly opposite the end portions of the openings to provide baffles by Which the How of liquid through the radiator element Will be broken up and deflected so as to cause the liquid to circulate throughout the chamber in each unit. The units may be formed rectangular in plan as shown in Fig. 2, or they may have any other desired form of outline, for example,

the units may be shaped in the forni of equilateral triangles as shown in Fig. 3, inwhich event the 4elongated openings on the opposite walls of the unit will be disposed in diagonal relation to each other.

In the form or' the invention shown in Figs. 4 to 8 inclusive7 the' openings in the walls of the units are offset or" staggered in relation to each other, which construction necessitates the liquid traveling in a zigzag course from one manifold to the other.

I claim:

l. In a radiator, a series of hollow sheet metal units each of which comprises top and bottom plates secured together at their edges and each of said plates having an opening, spacing ianges surrounding said openings extending outwardly from the plates and forming raised portions adapted to seat on the raised portions of adjacent units, said units beingv soldered together at their raised portions, plates extending over the upper and lower units, walls secured to said plates extending alongside the units, and shoulders on said walls extending under the opposed edges of said units holding saine in spaced relation to each other.

2. In a radiator a Jair of s aaced threaded y nipples, a series of superposed separable hollow units interposedv between said nipples and having open communication with each other, detachable threaded connections between the end units and the nipples, and vertical walls extending alongside the superposed units and engaging the edges thereof tor supporting the units in spaced relation to each other.

3. In a radiatona unit formed oit' horizontally disposed spaced walls connected together at their edgesa said walls each having raised portions surrounding an opening therein, said raised portions having fiat end walls forming the margins of the openings adapted to seat on the raised portion of an adjacent unitand to be detachably secured thereto by a soldered joint whereby intermediate units in a series thereof may be renioved and replaced without detaching other units of a series and vertical walls arranged alongside the units and engaging the edges thereof for' supporting the units in spaced relation to each other.
